Sometimes the best bonding experience a man can have with his son is to share in a sense of wonder and grandeur. There is no doubt that staring over the rim of the Grand Canyon in the Arizona desert will inspire just such sensations. After that's done, plan a hike down to the Colorado River at the bottom of the canyon, look back up to the rim and marvel at the raw power of that river. Nothing can be better for a father and son than to conquer a piece of nature of this magnitude.
